Rihanna and Jay-Z might be two of the world's biggest stars, but according to UK rapper Tinie Tempah, they're both "very down to earth."

Having toured with RiRi and Jigga, Tinie revealed to M Is For Music, how mpressed he was with the 'Run This Town' collaborators for managing to stay grounded, despite their huge success.

Tinie said: "Rihanna and Jay-Z are really down to earth and nice people. It's really nice to see that when you get into a certain position that you can still remain very grounded.

"Somone like Rihanna especially, is just like a normal down to earth girl. Without all the smoke and mirrors and glitz and glamour, she could just be like a friend or somebody you went to school or college with and it's nice to see somebody remain so humble and so grounded after so much success."
